TYPE-WRITING MACHINE? Specification of Letters Patent.

Application filed June 19, 1911. Serial No. 634,079.

Patenhed Feb, 6, 1912.

To all whom it may concern:

Be it known that I, JOHN H. GAnsonN, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Type Writing Machines, of which the following is a specification. I

This invention relates to side gages which are usually provided on the paper shelves of typewriting machines for guiding the side edges of the Work sheets as they are inserted at the introductory side of the platen.

The object of my invention is to provide an improved, simplified, and inexpensively manufactured side gage that will not mar the visible portion of the paper shelf. and that can be readily attached to. machines already in use, and also readily assembled upon new machines in course of 1nanufacture. r i

According to this invention, a rail carried on brackets extends along the rear of the paper shelf near its upper end; a carrier is splined on said rail, and the paper gage is pivotally fastened to the carrier, and a spring connects the carrier with the gage to press it against the front portion of the shelf and prevent accidental lifting. Only the lower edge of the gage presses against the shelf, and its underside is out of contact therewith, to prevent marring when the gage is adjusted. A spring bears, against the carrier and rail to maintain the gage where adjusted. By reason of forming the device of twoportions, viz. a gage portion and a carrier portion, and pivoting these portions together, the device can be readily assembled on the machine, and is particularly adapted for attaching to old machines or those already in use, where, although the paper shelves may be set or sprung at various angles or may have deformities, the pivotal joint allows the gage the necessary freedom to conform to such shelf and its lower edge to press against it.

. In the accompanying drawings, Figure 1 is an end elevation, partly in section, of the platen and platen frame of an Underwood typewriting machine, showing these improvement". Fig. 2 is a pla n View of Fig. 1, partially broken away. Fig. 3 shows the gage as raised from the paper shelf.

The usual platen 1 is mounted in aplaten frame 2, which has a paper shelf 3 at the rear of the platen, and is provided at its upper edge with a rolled rim 4.

An upstanding projection 5 serves as a side gage for the paper sheets, and is bent up from a plate (3 which lies downon the face of thepaper shelf and is shifted 'therealong. A rail 7 is mounted on brackets 8, by means of screws 9, and the brackets are fastened to the platen frame 2 by the screws 10, which are usually employed to secure the stiffening bar 10 to the platen frame. Said gage is attached to a bracket or carrier 11 on rail 7, for adjustment along the shelf 3; the carrier 11 having bent ends 12 to form a yoke with bores 13, whereby itis mounted upon the rail 7. The carrier is splined on said rail, by means .of a spring 14, pressing a roller or key 15 into a groove 16 in the rail 7, whereby the carrier 11 can be freely moved along said rail for adjust- 'ment of the gage, and maintained against,

accidental displacement by the pressure of spring 141-. Ears 17 on carrierdl carry a rock shaft 18 to which'is fastened the gage 5, the plate 6 thereof curving over the rolled rim 4 and extending to said rock shaft 18, to which it is attached by its cars 19. A spring 21. having one end fastened to car 17, and coiled around rock shaft 18, presses with its other end against the edge 20 of plate 6. and thereby maintains the gage against the shelf 3; the gage being so disposed that only its lower edge '21 presses against the shelf, while the underside of the gage is not in contact therewith, as shown in Fig. 1, so that the visible part of the shelf cannot be marred or scratched when the gage is adjusted therealong'.

It will. be evident that the gage can be readily assembled on old machines. for after brackets 8 have been fastened to the platen frame, the pivotal joint at affords the necessary freedom for the gage'to pass over the rim 4, as shown in Fig. 3, and also allows the plate 6 to conform to the shelf 3 and its edge 21 to press thereagainstfieven though the shelves of older machines be set at differ ent angles or even if they have some doformities.

Having thus described my invention, 1.

claim: a

1; in a typewriting machine, the oombi the introductory side thereo nation with a platen and a aper shelf at f: of a rod on said shelf, a carrier splined on said rod, a gage hinged to said carrier, and a spring pressing said gage against the shelf.

2.-In a typewriting machine, the combination with a platen and a paper shelf at the introductory side thereof, of a rail extending along said shelf, a carrier mounted to travel on said rail to permit adjustment therealong and being secured against transverse movement, means to hold the carrier yieldingly against said rail to prevent accidental displacement, a gage secured pivotally to saidearrier, anda spring pressing said gage against the shelf.

3. In a typewriting machine, the combination with a platen and a paper shelf at the introductory side thereof, of a rail extending along said shelf, a carrier mounted rotravel on said rail to permit adjustment therealong, a gage secured pivotally to said carrier, and a spring pressing said gage against the shelf; the under side of said gage being out of contact with said shelf.

4:. In a typewriting machine, the combination with a platen and a paper shelf at the introductory side thereof, of a rail extending along said shelf, a carrier mounted to travel on said rail, and a gage secured pivotally to said carrier to adapt it to proper disposition on the shelf.

5. In a typewriting machine, thecombination with a platen and a paper shelf at the introductory side thereof, of a rail extending alonglsaid shelf, a carrier mounted to travel on said rail, a gage secured pivotally to said carrier to adapt it to proper disposition on the shelf, and a spring pressing said gage against the shelf to prevent accidental lifting or displacement.

6. In a typewriting machine, the combination with a platen and a paper shelf at the introductory side thereof, of a rail extending along said shelf, a carrier mounted to travel on said rail, and a gage secured pivotally to said carrier to adapt it to proper disposition on the shelf and to facilitate attachment of said parts to the paper shelf.

7. In a typewriting machine, the combination with a platen and a paper shelf at the introductory side thereof, of a rail extending along said shelf, a carrier mounted to travel on said rail, a gage secured pivotally to said carrier to adapt it to proper disposition on the shelf, and a spring con necting said carrier with said gage for pressing the gage against the shelf.

8. In a typewriting machine, the combination with a platen, and a aper shelf at the introductory side thereof: of a carrier mounted at the rear of said shelf and adapted to .travel therealong, and a gage secured pivotally to said carrier to adapt it to proper disposition on the shelf.

9. In a typewriting machine, the combination with a platen and a paper shelf at the introductory side thereof, of a carrier mounted at the rear of said shelf and adapted to travel therealong, a age secured pivotally to said carrier to a apt it to proper disposition on the shelf, and a spring pressing said gage against said shelf to prevent accidental lifting or displacement.
